XStream is an open source java library to serialize objects to XML and back
again. Versions prior to 1.4.19 may allow a remote attacker to allocate 100%
CPU time on the target system depending on CPU type or parallel execution of
such a payload resulting in a denial of service only by manipulating the
processed input stream. XStream 1.4.19 monitors and accumulates the time it
takes to add elements to collections and throws an exception if a set threshold
is exceeded. Users are advised to upgrade as soon as possible. Users unable to
upgrade may set the NO_REFERENCE mode to prevent recursion. See
GHSA-rmr5-cpv2-vgjf for further details on a workaround if an upgrade is not
possible.
